3 Components and installation
3.1 Heating system Basic Line Ai1 Air BS 7010 / BS 7006
The newly developed heating system was designed as a compact air
source heat pump for outdoor installation. It is suitable for heating and
cooling low-energy buildings.
Thanks to the inverter-controlled compressor, the Basic Line Ai1 Air and BS
7010 operate extremely energy-efficiently. Due to the infinitely variable
adjustment of the power it impresses with high performance. Even at
outdoor temperatures of -15 °C, flow temperatures of 55° C are possible
The outdoor module contains all the heat pump technology (nicht der not
the condenser). The control moduel with the tank (Ai1 Air) or the hydraulic
module BS Hyd 5010 are installed in the building.
3.2 Structure and control
Complete hot water heating system with integrated central hot water supply
(option), consisting of: heat generator (heat pump), regulation and electrical
control, complete electrics and control system, semi-graphic display.
3.2.1 Electronic heat pump control
The heat pump control is included in the delivery scope of the
WATERKOTTE heat pump. Use in other than
WATERKOTTE heat pumps will void any warranty claim.
Info: Technical details, operation and warning messages (see
manual for heat pump control
The control is used to control and monitor heating systems that are operated with WATERKOTTE compact heat pumps according to technical guidelines of WATERKOTTE Wärmepumpen GmbH. All tasks to do with control
are fulfilled (depending on the external temperature, control, monitoring,
self-diagnosis, saving of data in case of breakdown, etc.
WATERKOTTE explicitly states that function warranty will become void if
used on systems not approved by WATERKOTTE. Any liability for consequential damages due to incorrect function within these systems shall be
explicitly excluded.

4 Transport to installation site
Modules of the Basic Line 7010 series are delivered ready-to-connect with
metal cladding. The Basic Line Ai1 Air / Basic Line 7010 are delivered ready
for connection.
Since the heat pump module weighs 120 kg or more, for instance, at least
two people are required for transport.
The devices are mounted on top of each other only at the installation site.
During transport it must be ensured that appropriate means of transport are
used (lift truck, transport rollers, handcart).
It is crucial that the heat pump is transported upright!
Transport in tilted position (45°) is permitted only temporarily during insertion. Horizontal transport results in oil displacement in compressor and can
cause damage to the heat pump during start-up.
After carton is removed or opened it is not permitted to tilt the module by
applying pressure to the pipelines or housing enclosure; this could result in
bent housing parts and pipelines.
4.1 Environmental conditions for installation (indoor module)

5.1 Installation and connection of indoor unit
To make hydraulic connections, you must use the supplied material (connecting lines and gaskets).
During assembly of connecting lines, use an according tool as brace to
prevent damage to the heat distribution station.
Installation of the indoor unit must be performed on a flat and horizontal
surface.
Wall clearance (free space) in front: at least 1000 mm.
Due to the connections on the rear of the unit, the mounting distance to
the wall (rear, right side, left side) must be selected in such a way that
access is ensured in case of repairs.
Recommendation for good service accessibility: Wall clearance (free
space), left, right 400 mm. Wall clearance rear at least
300 mm.
Figure 1: Recommendation - wall clearance for installation
5.2 Environmental conditions for installation
When selecting the installation site, observe the minimum volume under
consideration of the refrigerant applied (as per EN 378-1).
The room must be dry. Room temperature should be between +5 °C and
+25 °C. To facilitate maintenance, the use of a base plate is recommended.
To compensate for minor unevenness, we recommend use of an approx.
10 mm thick rubber mat.
